TURN provides dynamic and interactive simulation for low speed turning manoeuvres along a specified tracking path which includes cars, trucks, articulated vehicles, trailers, commercial aircraft and forklifts. Easy track path definition and creation with smallest turning circle calculation. TURN Vehicle Simulation
| "Even when designing a shopping centre these days, you need to see where the trucks can turn to get in and out of the loading yards." Hannes Kotze, ZII, Cape Town "The Observatory Business Park was designed with the help of TURN. We wanted to ensure that the large delivery trucks could drive through the traffic circles of the business park with ease." Peter Wium, De Villiers Sheard, Cape Town |

Multiple Vehicle Libraries Including Trh17 Criteria Vehicle Libraries are completely user configurable. Libraries for TRH 17 design vehicles and various aircraft are distributed with the program. You can create new libraries and add your own vehicles to the library by simply entering the dimensions for the new vehicle into a graphical vehicle dimension dialog. | ![]() |

User Configurable Vehicles You can create new libraries and add your own vehicles to the library by simply entering the dimensions for the new vehicle into a graphical vehicle dimension dialog. A full range of vehicle configurations is supported. Single unit vehicles include passenger cars, buses, trucks and forklifts. Trailer and semi-trailer combinations such as cars with trailers, articulated vehicles and interlinks are also supported as well as nose-steer and tail-steer aircraft. |
Define Way Points Along The Track Path Indicate the starting position and direction and then graphically indicate a series of way points. The vehicle will automatically move to the way points conforming to its minimum steering angles. To finish off your drawings you can place a vehicle profile, complete with dimensions, by simply selecting a toolbar button and indicating the position of the profile graphically. | ![]() |

Easy Track Path Definition And Creation It has been designed for ease of use. You simply draw or select the vehicle path, select the vehicle for the simulation, and then specify either a forward or a reverse run to create the track or swept path envelope. |
Smallest Turning Circle Calculation You can generate minimum turning envelopes by simply indicating a start position and an initial direction of movement. You can then drag the entire envelope to check critical sections of intersections, traffic circles and parking areas. |

Cargo Point Tracking Function Additional points, within or beyond the vehicle's body, can be tracked using the Cargo Point Tracking function. This allows you to track the position of cranes, side mirrors or cargo extremes along the track path. |
Forward And Reverse Movements Forward and reverse movement for any of the supported configurations can be simulated along a specified track path. | ![]() |

Plot Output Graphs And Data Tables Output graphs which are displayed for every simulation can be used to determine how close the design vehicle is to any point along the path at its maximum steering angles |
Track Path To Cad Layer With Test Vehicle Profile When a simulation is run, the path of the tyres can be displayed as a CAD layer. | ![]() |

Works In Conjunction With Existing Cad Entities CAD lines can be used as tracking paths and other CAD entities can be used in conjunction with TURN simulation. |
